ENZYMES-BIO-EOC

Front

Enzymes are composed of which macromolecule?

Back

protein

Front

At 50 °C, how will the enzymes in bacterial cells that function best at 70 °C or higher be affected?
Enzymes work best at an optimal temperature.

Back

The enzymes will not increase the rate of reactions as much as they would at 70 °C.

Front

What is the relationship between enzymes and activation energy?

Back

When an enzyme catalyzes a reaction, it decreases the activation energy of the reaction.

Front

How would the enzyme in meat tenderizer be affected if the meat is coated with tenderizer and then placed in a refrigerator? Temperature can affect how an enzyme works

Back

It would break down the meat more slowly

Front

Effect of pH 3 on enzyme with optimal pH 7-9
Enzymes work best at an optimal temperature and pH

Back

make it inactive

Front

The graph shows how the activity of an enzyme changes over a range of pH values. Which conclusion can be drawn? Options: pepsin works best at a pH near 2, pepsin works best at a pH of 9

Back

pepsin works best at a pH near 2

Front

What is another name for the substance labeled "catalyst" in a biochemical process?

Back

Enzyme

Front

Connection between body temperature and enzyme function: The human body maintains a temperature of around 98.6 degrees at all times. Enzymes are involved in almost every chemical reaction in the body.

Back

Enzymes function best at a specific temperature.

Front

Why are enzymes necessary for many cellular reactions?
Enzymes speed up reactions

Back

The reactions are too slow to meet the needs of the cell if enzymes are missing.

Front

Enzymes interact with the substrate at the

Back

active site
